Description
Technical field
The present invention relates to building material field, more particularly to a kind of water-proof plugging material and preparation method thereof.
Background technology
The construction of water-repellent paint is broadly divided into brushing, roller coat, blade coating, the form of construction work of spraying.But no matter which kind of construction party
Formula, the state of basic unit can all directly affect the effect of waterproof construction, and basic unit is loose, and cracking, dusting, water absorption rate is too high, and basic unit
Can have a great impact to the adhesive strength of water-repellent paint, put aside the settlement issues of later stage building, it is this obvious
Basic unit's problem can all cause water-repellent paint to play drum, and cracking, pinprick, phenomena such as peeling, these phenomenons can substantially reduce water-repellent paint
Integral waterproofing effect.
Basic reinforcement material on the market is broadly divided into now：1st, the liquid surface inorganic agent of polymer, this interfacial agents
There can be preferable consolidation effect to basic unit, can play and fix the sand, reduce the effect of basic unit's water absorption rate, but this inorganic agent runs into base
Layer can not be handled when having crack, it is still necessary to basic reinforcement can be just carried out after crack is repaired.2nd, cement mortar is handled,
Cement mortar, which has carried out base treatment, can solve the problems, such as that basic unit has crack or dusting, but a slow drying speed, long construction period,
Human cost is high, and whether can reach requirement in the presence of consolidation effect caused by the difference of construction gimmick.3rd, waterproof mortar, waterproof
Mortar although have waterproof and it is levelling the effect of, but waterproof mortar is not particularly suited for the earth construction of building, heavy with building
Drop, rigid waterproof mortar course occur crack, entered without waterproof effect.
The first common at present rapid-hardening loss circulation material is sulphate aluminium cement cement system, because it is mainly used in blocking up
Leakage, product do not possess mobility, and for largely plus after water, present leak stopping product can to cause because the ratio of mud is excessive
Powder is played, bonding is insecure, is not used to basic reinforcement.Second is self-leveling material, and it has larger mobility, can be used for
Basic unit is levelling and reinforces, but because its construction requirement is higher, so longer operable time is needed, and its levelling agent mechanism is logical
Crossing adjustment amount of water makes mortar have higher fluidity, but still needs to manually strike off, and needs certain thickness, in cost and manually
Etc. inferior position be present.
The content of the invention
In view of this, the embodiments of the invention provide a kind of water-proof plugging material and preparation method thereof, main purpose is to carry
The combination property of high water-proof plugging material.

Material.
Above-described embodiment 1-4 water-proof plugging material performances prepared are tested, test result is shown in Table 1.
The performance test results of water-proof plugging material prepared by the embodiment 1-4 of table 1.
By the test result of table 1, water-proof plugging material drying time, mechanical property and heat resistance of the invention
It is good.
The design principle of the present invention is by sulphate aluminium cement and perhafnate acid salt cement collocation washing river sand and heavy
Calcium carbonate adds a variety of auxiliary agents, improves formula intensity and application effect, adds re-dispersible glue powder, and rubber powder is dissolved in water with cement and entered
OK, cement carries out hydration, surface evaporation or basic unit's absorption, causes the free moisture of internal voids constantly to consume, makes latex
Continuous film not soluble in water is formed after particle drying, so that mixing and stirring material more densification after hardening, there is excellent globality.
Using powder levelling agent, the process such as levelling is on the one hand easier to after pouring, while the pinprick on surface can be reduced using levelling agent
Phenomenon, increases the adhesive property of glue for tile or waterproof material and this material, while can strengthen case hardness.Manually the later stage does not scrape
It is flat, you can to realize the effect of automatic levelling.Either big surface construction or small range construction can use.Using water-loss reducer,
It can meet not settle under higher amount of water, while can meet that product is used for that basic unit to be levelling and basic unit under high amount of water
Reinforce, bright water blocking is used under amount of water and is leaked, inner corner trim smears the techniques such as arc.
Water-proof plugging material of the present invention is compounded using sulphate aluminium cement and perhafnate cement, because of sulphate aluminium cement and
Perhafnate cement self-characteristic, material have excellent anti-permeability performance in itself, and two kinds of cementitious composites are compared to normal silicate
Cement is finer and close, there is faster rate of set, and setting time is fast, and getting up early intensity is high, effectively shortens construction period, accelerates to apply
Work progress.
The water-proof plugging material of the present invention uses modified glue powder, on the one hand improves the bulk strength of material, simultaneously modified
Rubber powder is more closely knit after material solidification, there is certain water-fast anti-permeability performance.
The water-proof plugging material of the present invention uses powder levelling agent：It is simple to can reach construction, surfacing can be straight after final set
Tap into the processes such as row ceramic tile plaster.
The water-proof plugging material of the present invention uses powdered whiting：Gap that can be effectively between filling powder, make material into
Type is finer and close, and powdered whiting and modified glue powder combination excellent effect.
Disclosed above is only the embodiment of the present invention, but protection scope of the present invention is not limited thereto, and is appointed
What those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should using above-mentioned scope of the claims as
It is accurate.
